My research indicates that my RDA for Vitamin B12 is 2.4 mcgs. The Polyvite O provides 70 mcgs per day. Is this okay to go over my RDA? Also, I was using the Healthy Habits B12 patches twice a week. However, those are 1,000 mcgs, way over my RDA. Anybody have any advice for me regarding this? Thanks.

What sources do your research draw from? If it's government sourced it's not that good. RDA's from public sources often do not allow for enough vitamin to be delivered to go to work on illness or chronic damage in the body - in other words, just "enough to get by on" each day.

Do you have a physician that says 1000 mcgs of B12 is too much for you?

I would trust Dr. D's decisions about the B12 and in thinking about the Polyvite version, know that it would be in a deliverable form that would (probably ) prevent you from getting painful shots of B12 later as your intestines continue to age.

I have been taking Dr D's Methyl 12 Plus for over six months and it has 1,000 mcg. I also take catecol which has 25 mcg's I also take Exakta which has 7.5 mcg's. I have read of people taking 3000 mcg's a day in supplement form without any problems. plus I am probably getting some from the food i eat. and everything seems to be improving with my health.

RDA is a suggested minimum level.

Many breakfast cereals are fortified to contain 100% RDA in a single serving.

A single serving of beef also provides about 100% RDA.

Therefore, you may be getting many times the RDA every day just from normal food. There are some things you want to avoid getting too much of as well as too little. For some people 1000 mcgs per day in supplement may be too much and for some others it may not be enough.

The RDAs in general is "the minimal amount needed to prevent deficiency diseases" rather than "the optimal amount for good health." Optimal amounts of many nutrients are much higher than the RDA, and the upper safe limits can be WAY above that! The RDA for B vitamins in particular is much, much lower than the safe limit.

If you're doing your own research on vitamins, don't just look at the RDA. IMO, the only value of finding out the RDA is so you can figure out the total amount of a nutrient in packaged foods, since those foods list % of RDA rather than actual amounts. What you want to research is "toxic doses" of nutrients (to avoid) and "optimal doses" (amounts to aim for.) Read from a few different sources, so if there's any discrepancy in the recommendations, you can learn more about the nutrient and make your own judgement about it.

does anyone use mineral taters to see if they are deficient in a particular thing.

I am getting a kit with 9 , I think' minerals in solution and if you can taste the mineral you might be deficient in it if you can then you are unlikely to be deficient. ( I think it's that way round lol.

I got the RDA figure from the NutritionData website, Daily Needs Calculator. It is actually called "Recommended Minimum Daily Needs" and not RDA. My current conclusion is that I shall continue with Dr. D's Polyvite O, but greatly reduce and eventually eliminate my usage of the Healthy Habits B12 patches. Thank you everyone for your feedback on this, I appreciate it.

and if you can ..... if you can then you are unlikely to be deficient. ( I think it's that way round lol.

Yummy false positives :D

There isn't a feasible toxic load for methyl b12.

Take any amount from assorted supplements. But at some point you'll just be peeing it out probably.

B6 is the one you have to watch for safety. Too much causes neurological damage. Luckily that amount is very high so you'd have to be taking some pretty crazy doses; or pounding energy drinks with vitamins all day.

One factor we should not miss while fixing the daily doses is the ability of our liver to store a particular mineral or vitamin. For example, liver can store B12 for up to three to five years' body requirements!

Where are the specific meal plans for the Genotype diets? In the book on pg 306, it says there are meal plans on the website. Could someone help with this? Thanks!

The meal plans that book mentions were part of a paid for Website that no longer exists. The company that ran the website charged $5 per week to access the content of their site. Most of the content that was on that site is now on http://www.genotypediet.com/ for free.

The meal planner is not.

SWAMI include a meal planner. It has a one time charge of $70 (Which you would have in 14 weeks of the other site).

Having mentioned the meal planner, I feel obligated to point out that I do not like the meal planner in the current release of SWAMI, so I cannot recommend spending $70 to get the current meal planner. The other material in SWAMI is great and well worth the $70.

------

The meal planner in the next release of SWAMI Xpress is much improved. Current SWAMI Xpress users will be automatically upgraded for free to SWAMI Xpress 2 when it is released.

Hi PC! I use the questionnaire in Patrick Holford's book. It is very thorough and detailed.

I usually don't make supplement decisions without some professional guidance.

I get tested every 3 or 4 months by a very good naturopathic practitioner. My very first complete health review over a year ago showed I was deficient in B12, which was no surprise to me since we eat so little meat. She recommended the Healthy Habits patches and WOW, what a difference they made in the way I felt! Subsequent tests have not shown a B12 deficiency and I am down to using one patch every 5 or 6 days instead of the original twice a week. My MD doctor thinks this is a good plan for me also.
